To all whom t 'may concern.' v l lBe it known that I, JOHN JAY MERREN, a citizen of the United States, anda resident of Porth Arthur, in the county of Jefferson and State of Texas, have invented certainv new and useful Improvements in Self-Lining Interlocking Building-Blocks, of which the following is a specification.

My present invention relates generally to building blocks, and more particularly to an interlocking building block which will permit of the formation of strong insulated and properly lined walls without the use of skilled labor and with or `without reinforcements as may be desired, and further objects reside in the particular construction of the block as hereinafter described with respect to the accompanying drawings, forming a part of this specification, and in which,

Figure 1 is an elevation of a section of wall formed with my improved blocks,

Fig. 2 is a top plan view thereof,

Fig. 3 is a vertical section taken on line 3-3 of Fig. 1,

Figs. 4, 5 and 6 are respectively a side view, top plan and end view of my improved wall block, and

Figs. 7, 8 and 9 are respectively a side elevation, top plan and end elevation of a corner block.

Referring now to these figures and particularly to Figs. 4, 5 and 6 my invention proposes a block having a rectangular body 10 whose inner and outer surfaces 11 and 12 are directly opposite one another, said body having ribs 13 and 14 extending along one side and one end and joined with one another to form a continuous outstanding web offset with respect to the inner and outer surfaces 11 and 12.

The body of the block is provided along its opposite side and its opposite end with grooves 15 and 16 opposite to and alined with the ribs 13 and 14 and are of just slightly greater width and depth than these ribs in order that each block be adapted to receive in snugly interfitting relation, the rib portions of the adjacent blocks in a wall.

As seen particularly in Figs. 5 and 6 it will be noted that the ribs and grooves of each of the blocks are located nearer to the outer surface 12 than the inner surface 11, permitting the body of the block to be pro- Specification of Letters Patent.

vided with grooves 17 and 18 alongmone side and end coextensive with the ribs 13 and 14y so that the weight of the finished blocky may thusbe ycontrolled by the relative depth and ,width of the last mentioned grooves 17 and 18 and yfor a full weight block these grooves may be dispensed with altogether.

Each block is furthermore divided into two side sections, at a point between the inner surface 11 and the alined ribs and grooves, and a sheet of insulating material 19 of any suitable nature is interposed between these sections so that capillary attraction is thus broken up and communication of moisture from the outer surface 12 to the inner surface 11 is prevented, the two side lsections of the block, so insulated from one another, being reinforced in connected relation by Z-shaped ties or reinforcements 20.

For corner blocks such as shown in Figs. 7, 8 and 9 and whose general structure embodies all of the features previously described with respect to the block of Figs.

4, 5 and 6, the body 10 of the block is further provided at one end with an angular offset extension 21, the space between which and the adjacent end of the block is adapted to receive the end rib 14 of the next ad jacent block at right angles thereto in a wall, as particularly shown in Fig. 2.

Thus as seen. in Figs. 1, 2 and 3 the blocks may be readily staggered in the several vertical courses 22, 23 and 24, the grooves 15 and 16 of each block except those of the lowermost course, receiving portions of the side ribs 13 of two blocks in the next lower course and the rib 14 of the next adjacent block at one side in the same course so that an extremely effective bond is thus formed and vertical alinement of the blocks in the wall assured without the necessity of particular skill in their relative disposition.

Semi-fluid cement may be placed with brushes for instance on the ribs as the successive blocks are laid and it is obvious that additional wall reinforcements may be utilized and embedded if so desired in the channels of the wall formed by deepening the grooves 15 and 16 of the blocks so that they are deeper than the' corresponding ribs. It is furthermore obvious that pointing and other work requiring the services of skilled mechanics is thus done awayrwith and a 'Wall formed Whose inner `andonter surfaces are smooth and continuous providing forkeiieotive decoration throughout a Wide range of choice and it isto be under# stood that I may dispense Withthe insulating material 19 if so desired.

I claim:

" l. A huildinghlookhaving a rectangular facefthan the inner snrface,1said bloei; 'having .grooves along one edge and oneiend looated'between. its yinner sur'faee and the'rst mentioned ribs and grooves.

2.
